FIRST ORDER LINEAR DIFFERENTIAL EQUATION: The first order differential equation y0 = f(x,y)isalinear equation if it can be written in the form y0 +p(x)y = q(x) (1) where p and q are continuous functions on some interval I. Differential equations that are not linear are called nonlinear equations. SOLUTION METHOD: Step 1.

2.1. Linear Differential Equations A first order differential equation y0 = f(x,y) is a linear equation if the function f is a “linear” expression in y. That is, the equation is linear if the function f has the form f(x,y)=P(x)y +q(x). (c.f. The linear function y = mx+b.) The solution method for linear equations is based on writing the ...
